Why are dark-colored pocket mice more commonly found in locations with dark substrate?
A
They have a genetic mutation that only allows them to survive on dark substrates.
B
They are less likely to compete with light-colored mice for resources.
C
They are better camouflaged from predators, increasing their chances of survival and reproduction.
D
They are more efficient at finding food in dark environments.
Verified step by step guidance1
Understand the concept of natural selection: Organisms with traits that provide a survival advantage in their environment are more likely to survive and reproduce, passing those advantageous traits to their offspring.
Identify the environmental factor: In this case, the dark substrate serves as the environmental factor influencing the survival of pocket mice.
Analyze the role of camouflage: Dark-colored pocket mice blend in better with the dark substrate, making them less visible to predators. This reduces their chances of being preyed upon.
Connect survival to reproduction: Because dark-colored pocket mice are less likely to be eaten, they have a higher chance of surviving long enough to reproduce and pass on their dark coloration genes to their offspring.
Conclude the evolutionary outcome: Over time, the population of pocket mice in areas with dark substrate will have a higher proportion of dark-colored individuals due to the selective pressure exerted by predation and the advantage of camouflage.
